The high-value-added chemical reagent peroxydisulfate (S2O82-) was produced photocatalytically over noble-metal loaded WO3 powder suspensions in aqueous H2SO4 under flowing O2 and simulated solar light irradiation. Pt cocatalyst showed the highest photocatalytic activity for S2O82- formation of the studied metals (Au, Pd, Rh, and Ru). Further study indicated that continuous accumulation of S2O82- was achieved only over the Pt/WO3 photocatalyst.
在流动的 O2 和模拟太阳光照射下,贵金属负载 WO3 粉末悬浮液在水中将高附加值的化学试剂过二硫酸盐(S2O82-)光催化合成。Pt 助催化剂表现出对所研究金属(Au、Pd、Rh 和 Ru)中 S2O82-形成的最高光催化活性。进一步的研究表明,只有在 Pt/WO3 光催化剂上才能实现 S2O82-的连续积累。
